Recover recently deleted items does not work when there are calendar and other not email items present

I accidentally delete my inbox by accident tonight and ran into a lot of bugs in Outlook trying to recover my inbox from my deleted folder
1) Sorting Delete Items folder by date/time deleted was a very hard and multiple step process --- it should be easy.
2) Recovering recently moved/deleted items failed on me I think because I had some draft calendar appointments and other items that hung up the process and I almost LOST EVERYTHING but outlook didn't tell me why.
3) When I instead tried to move the items by copy and paste or drag and drop that failed too!
4) The solution was to drag and drop everything into a regular explorer folder so at least things were saved - no errors doing this. Then to one-by-one or just email items move to inbox. laborious.
Microsoft can do better.
Sincerely,
Robert
